what is Radio:
Radio word comes from the latin radĭus (‘lightning’) and has several Bridgat:
In geometry, the radio is the straight line that can be drawn from the center of a circle to the circumference. In this sense, a radio is also a rod that connects the center of a wheel rim. The word ‘radio’ is also used to refer to the circular extension of land, taking as a reference a point that serves as the length of the RADIUS and Center. In anatomy the radio is a bone of the human body that forms along with the ulna, shape the forearm. In chemistry, the radio is a chemical element in the periodic table. Its symbol is Ra and atomic number 88. It is a white and shiny metal with a high radioactivity. In telecommunications, the word ‘radio’ as a shortening of other words such as broadcasting, radio transmitter and radioreceptor.Como suffix prefix, ‘radio’ shows ‘radiation’, ‘radioactivity’, or relationship with the radio.
The radio in geometry
Radio is a girth is a segment joining the Center with any point of the circumference. All radii of a circle is the same length and they correspond with half the diameter. One way to find the radius of a circle is to calculate the square root of the division of the area between the number. The radio on a sphere is a segment joining the Center with any point on its surface. The radio or apothem in a regular polygon corresponds to the radius of the circumscribed circumference. In a regular polyhedron, the radio is correponde with the radius of the circumscribed sphere.
The Atomic RADIUS is the distance between the nucleus and the outer layer. The Atomic RADIUS allows you to set the size of an atoms and is usually measured in angstroms (A) or master (pm). For example, the Atomic radius of the iron is 1.26 to. Usually the Atomic RADIUS increases to descend in the table groups and decreases to advance along a period.
Radio as a means of communication
The radio as a means of communication is the shortening of words such as broadcasting, broadcasting, radio transmitter or radio transmitter. Generic term, means that the radio is a means of communication based on the emission and reception of signals of audio using electromagnetic waves. Its invention dates back to the late 19th century and its later development meant a revolution in the world of telecommunications.
Referred to a vehicle, the turning radius is the minimum distance at which a vehicle can turn on itself. In the field of engineering, sa talk radio turning to refer to a geometric scale of the cross-section of a mechanical Prism and one-dimensional resistant element. Kinematics, uses this concept indicating the radius of curvature of the trajectory of a particle.
The Ionic RADIUS is the distance from the center of the nucleus of an ion and farthest from the same stable electron. An example of ionic radius of an element is the iron (0.64 A).
